Welcome to our forum.
I was recently in a dealer who carried only full foam tubs and he was saying that the cheaper ones are thermopannel and the LIPA (Long Island Power Authority) has tested the full foam and showed they are very very energy efficient. I thought the thermopannel were effficent too until he told me he raw hard data.
I used to own an Emerald (a TP tub). One thing I know for an absolute fact is that I will never own a thermopane tub ever again.Reason why? My own "raw data" in the form of a sky high electric bill. The Emerald more than doubled my electric bill.Keep in mind that I live in Michigan. My wife and I were the only ones who used it so the cover was on most of the time.I bought the tub new and ordered it with as much insulation as I could plus Reflectix. When the electric bills started rolling in I went to Home Depot and bought a box of Husky garbage bags and faceless fiberglass insulation. I filled the bags with the insulation and lined the interior with them. Royal Spas uses this same method except theirs hangs neatly inside.I prayed to the hot tub gods for lower electric bills but they ignored my pleas. The DIY insulation did nothing for my energy costs. I sold that Emerald and we don't miss it one bit.Now the only hot tub I will buy is a full foam. I will be looking for one with a good base. I won't settle for one that is "sealed" with just a poly sheet. I think that is just a way for a manufacturer to cheap out.I can see a Jacuzzi 345 in my future but no Colemans or Arctic or Royal or Spa Crest. No thermopane ever again.
Please shift the thread to BADH.
As far as I know, Emerald does not offer a full foam option. Back when I was ordering mine a full foam option was never mentioned. I have not been to the Emerald website or read one of their brochures lately so fo all I know they may offer it now.One thing I think Emerald (and Arctic and Royal) does a wonderful job with is their fiberglass shell. No doubt they are strong. They will never have structural issues. Wish I could say the same of their insulating method. I guess there is good reason why most of the major manufacturers use full foam.....It Works!
Again, please don't lump Arctic Spas in the same category as the TP spas. They are not TP. Like I said before, in a third party independent test, Arctic Spas ranked right up there with some of the top FF spas, and even tested better than most. They are as energy efficient as any FF spa, even in cold weather climates like Michigan.
We are looking at a Sunrise that has neither Thermal Pane or Full Foam. It has Roxul insulatiion. It is a multi-layered instulation. Supposed to be much easier to work on if problems arise plus be great at insulating. It seems to me that full foam can be a major headache to repair...somtimes even having to send the hot tub out??? Is this true?? I know most have a 5 year warranty but lets's face it, you will probably have your hot tub a lot longer than that....so then what? I'm a newbie trying to figure it all out. Any truth to any of this stuff?crystal777
I wouldn't own a thermopane because IMO they just don't work as well as FF at avoiding heat transfer even if they promise their method works great and explain the theory. I do agree that Arctic is a different story because they don't follow the standard thermopane method and I can see why they don't like to get lumped in with the standard foil barrier methods.
Clearwater does their spas like Artic. It works great if done right.
